IMPROVEMENT m BAG-MACHINES.

Specification forming part of Letters Patent N 0. 190,663, dated May 15,1877; application filed March 14, 1877.

To all whom JIM concern:

Be it known that we, WM. P. ARNOLD and GEO. QUIGLEY, of Fredericksburg,in the county of Spottsylvania and State of Virginia, have inventedcertain new and useful Improvements in Machines for -Makin g Paper Bags;and we do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use it, reference being had to theaccompanying drawings, which form part of this specification.

Our invention relates to an improvement in machines for making paperbags; and it consists in the arrangement and combination of parts, thatwill be more fully described hereinafter, whereby the bags can bequickly and easily made, and then carried back out of the way by asuitable mechanism and deposited in a box under the table.

The accompanying drawings represent our invention. w

a represents a common table-like frame of suitable size and height, uponthe top of which are placed the two slotted guides b, which are joinedtogether at their upper ends by the cross-bar 0. Moving up and down inthe slots of the guides is the presser d, which is flat on its underside, and beveled from the rear edge down to a sharp edge at its front,so as to allow the bags being formed to be folded freely back over it.The ends of this presser extend through and beyond the guides, and havethe rubber or other suitable springs 0 attached to their upper sides, soas to instantly draw the presser upward as soon as the pressure of thefoot is raised from the treadle g. Just in the rear of the presser isjournaled a roller, h, which has ratchet-teeth at each end, and around"which passes the endless belt or apron 5. Se-

cured to one end of the V presser is a pawl, j, which catches in one ofthe teeth on one end of the roller every time the presser is drawndownward by the treadle, and then, as the presser rises upward, the pawldraws the roller partially around, thereby causing the belt or apron ito move backward over the rear edge of the table, and over the roller 1,secured thereto, and forward over a roller, 0, placed under the table.If so desired, the belt may be provided with sharp points orprojections, so as to insure its carrying the bags backward over theroller 1, and then forward, and depositing them in a box placed underthe front edge of roller 0.

Any desired number of any sized paper bags that have yet to have theirends pasted shut are placed in a pile on the table, so that the endswhich are to be pasted shall project a suitable distance in front of thefront edge of the presser. The operator presses down on the treadle, andbrings the presser down upon the top bag, so as to hold it firmly whilethe end is being pasted and folded. While the bag is thus held thefingers are inserted into its end, so as to open it wide, and then thetwo side edges are folded inward toward each other until they slightlylap, and then the four outside edges are pressed down all around, so asto form the bottom into as perfect a square as possible. The paste-brushis then used, and the two corners immediately in front of the operatorare then folded inward toward each other and made to lap. The operatorthen allows the presser to rise upward, and at once pushes the bag thathas just had its end pasted back out of the way, and then brings thepresser down, as before, not only on the next bag that is to befinished, but upon the one just moved back out of the way. As each onethat is finished is thus held for some time after being pasted, thepaste has a chance to take a thorough hold upon the bag, and slightlydry, and in this way the corners and edges never have a chance to becomeloose, as they always will where this pressure is not applied for sometime after the pasting. As one bag after another is thus finished andpushed back the top ones will be gradually moved back from under thepresser, and then the belt will take them and deposit them in the boxunder the table.

The endless belt here shown is but one of a variety of ways of carryingthe bags away from the operator as they are finished, as any othersuitable one may be used in its stead.

If desired, the springs-may be attached to the under side of thepresser, so as to keep it constantly pressed downward, in which case thetreadle would be used simply to raise the presser upward. The table mayalso be made 3. The presser d, beveled away at its front edge, so thatthe paper can be folded back over it while it is holding the bag,substantially as described.

In testimony that we claim the foregoing we have hereunto set our handsthis 14th day of March, 1877.
